If you're stressed, it will eventually show on your face. Stress causes your body to overload on certain chemicals and hormones, which can cause everything from wrinkles to oily skin. Chill out. To help lower stress, do yoga or other moderate, consistent exercise. Sleep and eat better.

Some women use 20 or more products in their beauty regimen. Doctors and dermatologists agree – that's overkill and you're wasting money without helping your skin. Two or three products at most in the morning and night. Two they all agree on: use a gentle cleanser (we'll go ahead and say it: COR!) and sunblock!

Hot water dries out your face. Sounds counterintuitive maybe, but really hot water removes all the healthy oil that your face uses to protect itself. (Yes a little oil is natural and good.) So drop the temp a few degrees to give your face a break!
